BELT SQUEALS

2002 Nissan Sentra • 140,000 miles

2002 sentra. Belt squeals when you first start car and turning wheel. Stops when your driving on the road, but will squeal again when you have the heater fan on.

That sounds like the power steering pump is going bad or the belt is worn our loose. It also sounds like the alternator is in the same condition.
What happens is the extra load on the accessory either makes a failing pulley bearing squeal or it makes the belt slip which squeals. Check the alternator pulley and power steering pulley for play to see if they need immediate replacement.

If the belt tension and conditions are good, check the harmonic damper on crank pulley.

Power steering fluid was leaking. The rack and pinon was replaced. It's not leaking now.
